possible Viewsonic VX922 problem?!

AvengerUK · 24 Aug 2006 at 14:11

Hi all,

Ive just finished running 3dmark 05 on my new install. During the first test, (return to proxycon?) i noticed a *possible* problem; it is most visible during this test, when the "big chain gun" is fired with a head-on view (but all the time in the distance/some other 'flashing' scenes). Basically, the flashs of light create black like tears along the screen, which are only caused by the screen (tested card by taking a screenshot!).

Does anyone know what causes this? and how i could perhaps, make it more bearable? - I know that in some games it does it also! - could it be due to running @1024 rather than 1280? (native rez)

Thanks for any advice!

Think you need to check whether vsync is on or off. Normally during a benchmark vsync will be off otherwise you will be limiting your frame rate severely. The normal operation for LCD's is to force vsync on in the gfx driver so it overides any game settings. Then set your refresh at a frame rate that your card can closely match or can do for sure.

e.g.

60Hz Refresh
Vsync forced on

this way my pc always try's to produce 60 fps which should sync with the monitor and not produce page tearing which is what you might be seeing.

Hope that helps.

yep, sounds very much like "tearing" caused by the graphics card and monitor not being synchronised. You can enable vsync which should stop this

Hi,

Thanks for your replys, however putting vsync on/off doesent make a difference with the 'Flashing' problem.

hen the "big chain gun" is fired with a head-on view (but all the time in the distance/some other 'flashing' scenes). Basically, the flashs of light create black like tears along the screen, which are only caused by the screen

- Also here the FPS doesent exceed 45FPS anyway

Ive tested on other screens, including a CRT and get the same results, exactly.

Any other ideas?

so you get the same problem when using your CRT? It won't be the screen to blame then, something in your graphics card more likely

Yup - although the black lines/tears etc that come about during 'Flash's' can only be seen in a moving image, ie screenshot's show nothing :/

Sounds like something a driver change might fix, have you tried that yet?
